Type, adult 9 , no. 3008 in the collection of the Instituto de Butantan, 

 Sao Paulo, Brazil. It was collected in Ilheos, Bahia, Brazil, and is dedicated 

 to Professor Piraja da Silva, director of the branch the Instituto de Butan-

Bothrops pirajai is very different from all the other Brazilian 

 species of Bothrops, which have the 2d upper labial in contact

 tinguished by the following characteristics. 



Internasals and canthals 

 Ventrals 



Postocular streak 

 Dorsal markings 



B. pirajai 



Small. 

 164. 

 Absent. 



Black A-shaped mark- 

 ings separated by

B. jararacussu 

 Very large.

 from the ventrals. 



Bothrops neglecta sp. nov.
